I haven’t seen a study that empirically shows that it’s helpful. There is certainly a false myth that we need eight hours of continuous sleep: I think it’s possible to have your sleep be a little bit broken up and be perfectly healthy—but getting that eight hours is crucially important. The thing is that the placebo effect in some of these polyphasic sleep methods runs really high.
Clinical trials have shown that passion flower can reduce anxiety as effectively as the prescribed drug known as benzodiazepine oxazepam. A four-week, double-blind study of patients with generalized anxiety disorder compared passion flower to the common anti-anxiety drug. While the oxazepam worked a little faster, both were the same in terms of effectiveness — however, the passion flower did not cause problems with job performance, such drowsiness while on the job, unlike the oxazepam.

If you’re American, chances are you aren’t getting enough sleep. A Gallup poll (2005) of Americans past age 50 found only 32% reported getting a good night’s sleep routinely. 56% said they got between 6 and 8 hours a night. The US Dept of Health and Human Services reports that “The odds of being a short sleeper (defined as someone who sleeps less than 6 hours a night) in the United States have increased significantly over the past 30 years.”
Some of our expectations regarding our sleep might be slightly misguided. As an example, the thought that we will fall asleep almost immediately upon retiring to our beds may be improper. It should normally occur in less than 15 to 20 minutes, but it may take as long as 30 minutes as we get older. In fact, people who fall asleep in less than five minutes may be "pathologically sleepy." This means that they are so sleepy that they fall asleep quicker than might be normal. In some cases, this ability to fall asleep quickly—and enter rapid eye movement (REM) sleep quickly—can be seen in excessive daytime sleepiness that might occur in sleep deprivation or narcolepsy.
Getting in sync with your body’s natural sleep-wake cycle, or circadian rhythm, is one of the most important strategies for sleeping better. If you keep a regular sleep-wake schedule, you’ll feel much more refreshed and energized than if you sleep the same number of hours at different times, even if you only alter your sleep schedule by an hour or two.
If anxiety is keeping you up at night, try these natural sleep remedies: yoga, meditating, or writing in a journal before bed. Tai chi is another powerful sleep-inducing (and stress-reducing!) exercise; in a 2004 Oregon Research Institute study, a tai chi routine right before bed helped people fall asleep 18 minutes faster and get 48 minutes more nightly sleep. In addition to adopting sleep-inducing habits, avoid these 11 “harmless” habits that are causing your insomnia.
It can be much harder to get yourself off to sleep if you are worried that you are worried that you're going to be tossing and turning just a few short hours from now, so try to stop yourself waking up a lot in the night. One of the main causes of waking in the night is through back pain, so try to minimise this by buying a decent mattress - and make sure you change your mattress every 8-10 years. Also taking an anti-inflammatory such as ibuprofen before you go to bed can help ease muscle spasms in the night.
A regular meditation practice may help to promote sleep by slowing breathing and reducing stress hormone levels. Meditation is a technique that involves consciously directing one's attention to an object of focus (such as breathing or a sound or word) in order to increase awareness, relax the body, and calm the mind. Some types of meditation include guided meditation, vipassana meditation, yoga nidra, or body scan. Also try:
Some small studies have suggested that magnesium can help with insomnia, but the research isn’t conclusive. One study found that while total sleep time didn’t change significantly for participants receiving magnesium supplements, there was improvement in the participants' Insomnia Severity Index score, which measures the nature, severity, and impact of insomnia in adults, as well as improvement in sleep onset latency (the length of time that it takes to fall asleep), sleep efficiency, early morning awakening, and more.
Exercising in the morning may help you sleep better than working out in the afternoon or evening. In an unpublished study presented at the 58th meeting of the American College of Sports Medicine, researchers at Appalachian State University in Boone, North Carolina, found that people spent 85 percent more time in light sleep and 75 percent more time in deep sleep when they worked out at 7 a.m. compared with working out later in the day. The authors aren’t sure why, but they believe early-bird workouts affect levels of stress hormones in a way that leads to better sleep quality later on. More research is needed to confirm these finding.
Did you know that a lack of exposure to sunlight may be interfering with your sleep quality? Light exposure is crucial to our circadian rhythms (aka our internal clocks), which control vital biological processes including sleep. Scientific research reveals that that a lack of light in the workplace results in poorer overall sleep quality, as well as sleep disturbances, which can then have further negative effects on health.
Adjust the thermostat. If you’re too hot or too cold at bedtime, sleep isn’t going to come easy. While there’s no ideal temperature for everyone, most people sleep comfortably when the bedroom is between 60 and 67 degrees. As you start to feel drowsy, your body temperature drops, which in turn helps you drift off to sleep. A cooler bedroom facilitates that. Don’t cool it off too much, though — shivering in bed isn’t conducive to a good night’s sleep.
